Abstract
In order to promote the adhesion of a crimp terminal (10) to an aluminum electric wire (100) by virtue of crimping to thereby realize an improvement in electric connecting performance, the thickness of tin plating applied to an inner surface of a conductor crimping portion (13) of the crimp terminal (10) is set to be in the range from 2.1 μm to 5.0 μm, and then, the conductor crimping portion (13) is crimped to a conductor (100a) of the aluminum electric wire (100).
Claims4
A method for crimping a terminal to an aluminum electric wire, comprising:
- preparing a terminal having an electric connecting portion which is configured to be connected with a mating terminal at a front end side thereof, and a conductor crimping portion which is configured to crimped to a conductor of an electric wire configured to be connected therewith by bent inward to be crimped at a rear end side thereof, wherein at least an inner surface of the conductor crimping portion is plated with a metal whose hardness is lower than a hardness of a metal of a terminal base material, and a thickness of the metal applied to plate the inner surface is set to be in a range from 2.1 μm to 5.0 μm;
- preparing an aluminum electric wire having a conductor made of aluminum or an aluminum alloy as the electric wire configured to be connected with the conductor crimping portion;
- and
- crimping the conductor crimping portion to the conductor of the aluminum electric wire by bending the conductor crimping portion inwards in a state that the conductor of the aluminum electric wire is inserted into an interior of the conductor crimping portion of the crimp terminal.
